That is good to know, thank you. I am considering buying one I like and My fiance likes a different one. So I thought get both and didn't know if i could save room by housing both but since it is a very bad idea I wont.
I have housed pairs of equal size together without issues but I still would not suggest doing so... Careful measures need to be taken to house kings together... It is much easier and safer to give one its own cage or bin... Bad things can happen... Kingsnakes have even been known to try and eat themselves...
